Marc D. Hauser (25 October 1959) is an evolutionary biologist who teaches at the Psychology Department at Harvard University.

Biography

He received a BS from Bucknell University and a PhD from UCLA. Currently, Hauser is a Harvard College Professor, and Professor in the Departments of Psychology, Organismic & Evolutionary Biology, and Biological Anthropology. He is the co-director of the Mind, Brain, and Behavior Program at Harvard, Director of the Cognitive Evolution Lab, and adjunct Professor in the Graduate School of Education and the Program in Neurosciences.

Hauser's research sits at the interface between evolutionary biology and cognitive neuroscience and is aimed at understanding the processes and consequences of cognitive evolution. Observations and experiments focus on nonhuman animals and humans of different ages and mental competence, incorporating methodological procedures and theoretical insights from ethology, infant cognitive development, evolutionary theory, cognitive neuroscience and neurobiology. Current foci include: studies of language evolution, the nature of moral judgments, the development and evolution of mathematical representations, comparative studies of economic-like choice, the precursors to musical competence, and the nature of event perception. One of his research projects is internet based 'The Moral Sense Test' in which the participant is presented with a series of hypothetical moral dilemmas and is asked to offer a judgment regarding each one.

In August 2010 it was announced that Hauser had decided to take a leave of absence from Harvard, after a three year long internal investigation found evidence of scientific misconduct. The results of this investigation have not been publicly released and the lack of transparency in this investigation has evoked substantial speculation about what the investigation actually uncovered. According to a report in The New Scientist, unnamed scientists in the field have claimed that Harvard decided to investigate Hauser's lab after students who had worked there made allegations of data falsification. The NY Times quotes Michael Tomasello, another well-known animal cognition researcher and competitor of Hauser's, as claiming that some of Hauser's previous students personally told him that there "was a pattern and they had specific evidence ”. However, it could not be confirmed that any of Hauser's students has been in contact with Tomasello; in fact, he is not known to have any relation to Hauser's laboratory and the two laboratories are in competition. Tomasello also claimed that he has information from "a Harvard faculty member and from former students of Dr. Hauser" that the investigation found evidence for eight counts of scientific misconduct. However, Tomasello's claims have not been confirmed.

However, on August 19, 2010, The Chronicle of Higher Education reported the contents what it claimed to be an internal Harvard document. It was allegedly a statement from a former research assistant who said that Hauser falsely coded videotapes of monkey behavior, resisted his research assistants and students requests to have them recoded by another observer and then pressured his students to accept his false data. When they went ahead and recoded the data without Hauser's permission, they allegedly found that Hauser's coding bore little relation to what was on the tapes. According to the document, several other lab members allegedly had similar run-ins with Hauser. However, the authenticity of the document allegedly provided to the Chronicle of Higher Education has not been verified. Moreover, the Chronicle of Higher Education also notes that the research assistants and students reported the aforementioned allegations in 2007, while the data in question have been acquired in 2002 or earlier (see below). As a result, the research assistants must have been in Hauser's laboratory for at least five years or must have chosen to reanalyze five year old data for other reasons. Neither possibility appears to be typical for research assistants, and neither has been confirmed independently.

The allegations, thus far, center on a paper that was published in the journal Cognition in 2002 . In this paper, Hauser and his collaborators concluded that cotton-top tamarin monkeys can learn simple rule-like patterns. In two additional papers, some field notes or video recordings were "incomplete", although Hauser and his co-author have replicated the experiments. Proceedings of the Royal Society published the replication of the missing data in an addendum.. However, while the authors have submitted results that claimed to replicate data missing from a 2007 Science paper, the status of that paper is unclear. The new data are under review, but a spokesperson for Science stated that the editorial team is uncomfortable about making a decision without knowing the results of the Harvard investigation.

The NY Times reports that Gordon G. Gallup and Herb Terrace have long been skeptical of Hauser's methods. Gordon G. Gallup of SUNY Albany has raised concerns about a 1995 paper in which Hauser claimed to have found evidence that cotton-top tamarin monkeys can recognize themselves in a mirror. After reviewing the videotapes for these experiments, he found that “there wasn’t even any suggestive evidence” for Hauser's published results. In the field of animal behavior, disputes about methodology and disagreements about the interpretation of results are common. However, in this case, Gallup, who does not study cotton-top tamarins and has studied the same issue only in much larger old world monkeys and apes, could find no evidence for Hauser's reported effects in the video recordings. Indeed, in 2001, Hauser reported in the American Journal of Primatology that he had failed to replicate this earlier result. On Aug 12, a Harvard University spokesperson said that Harvard's findings will be reported to the appropriate federal funding agencies. They will conduct their own review and make their conclusions available to the public.

Awards

Hauser is the recipient of a National Science Foundation Young Investigator Award, a science medal from the Collège de France, and a Guggenheim Fellowship. He has published approximately 200 articles in major research journals as well as six books. His work has frequently been covered by The New York Times, The Wall Street Journal, The Boston Globe, and The Washington Post, and he makes frequent appearances on various NPR shows, as well as television and international radio.
